Embodiment 1

[0020] like figure 1 As shown, an LED lamp with a flexible transparent substrate includes a flexible transparent substrate 4, the upper surface of the flexible transparent substrate 4 is coated with a transparent conductive circuit layer 3, and an LED light source is welded on the transparent conductive circuit layer 3 2. The LED light source 2 is packaged with a flexible transparent film 1. The transparent conductive circuit layer 3 is connected to control each LED light source and connected to the drive circuit of the external circuit. The LED light source is a combination of more than one single-wavelength light source. Controlled by a driving circuit, various visible light colors are generated, and lights of different wavelengths are generated. The flexible transparent film 1 is specifically a PET film.

[0021] The transparent conductive circuit layer 3 is made of transparent conductive material, the transparent conductive material is metal film, such as ITO, or the trans...

Embodiment 2

[0024] like figure 2 As shown, in this embodiment, the upper and lower surfaces of the flexible transparent substrate are coated with a transparent conductive circuit layer, the LED light source is welded on the transparent conductive circuit layer, and the LED light source is packaged with a flexible transparent film. Other features and implementation of this embodiment Example 1 is the same.

[0025] The flexible transparent substrate of the present invention not only supports the LED chip, simplifies the structure of the lamp, reduces the thermal resistance of the entire lamp system and makes the LED lamp have certain flexibility, but also makes the light emitted from the bottom of the chip The light passes through the reverse side of the substrate to realize the full luminescence of the LED lamp.

Description

technical field [0001] The invention relates to the field of LED lamps, in particular to an LED lamp with a flexible transparent substrate. Background technique [0002] In the field of display, OLED uses organic materials to make light-emitting surface light sources through printing and other methods. It has strong flexibility and inherent advantages in bendability. However, compared with the LED, it not only has low luminous efficiency, low maximum power, short service life, but also a small light-emitting area, which cannot meet the needs of lighting applications. Contents of the invention [0003] In order to overcome the deficiencies in the above prior art, the present invention provides an LED lamp with a flexible transparent substrate. [0004] To achieve the above object, the present invention is achieved through the following technical solutions: [0005] An LED lamp with a flexible transparent substrate, comprising a flexible transparent substrate, the upper su...
